Can someone please tell me how to calculate the percent of error for a set of data points?

thanks so much!

Certainly! To calculate the percent of error for a set of data points, you can follow these steps:

1. Determine the accepted or true value for the quantity being measured. This value is typically obtained from a reliable source or a reference point.

2. Calculate the absolute error for each data point by subtracting the accepted value from the measured value. Absolute error represents the magnitude of the difference between the measured value and the accepted value, regardless of direction.

3. Convert the absolute error into relative or percent form. To do this, divide the absolute error by the accepted value and multiply by 100.

4. Repeat steps 2 and 3 for each data point in your set.

5. If you have multiple data points, you can calculate the average percent error by summing up all the percent errors and dividing by the number of data points.

Here is the formula to calculate the percent of error for a single data point:

Percent Error = (|Measured Value - Accepted Value| / Accepted Value) x 100

Please note that the percent of error calculation assumes that the accepted value is the true value. However, keep in mind that it is possible for the accepted value to have its own uncertainty or error associated with it.
